Detailed Description
Post traumatic stress disorder (PTSD) is a condition that develops as a result of exposure to a traumatic event and is characterized by intense physiological and psychological reactivity to stimuli associated with that trauma. PTSD represents a substantial proportion of the burden of illness among Veterans. A recent study found that PTSD was diagnosed in 13% of Veterans returning from Iraq and Afghanistan. Recent reports have also highlighted that PTSD is associated with suicidality - a fact that may explain the alarming rise of suicidal behavior amongst returning Veterans. Several studies suggest that meditation-based treatments may be helpful in treating PTSD. Sudarshan Kriya Yoga (SKY) is a meditation technique that involves a sequence of breathing exercises and has shown promise in treating PTSD. There are several lines of evidence to suggest that such meditation techniques provide a solid foundation for treating PTSD. First, breathing meditation techniques offer a powerful method for balancing autonomic nervous system activity that is often heightened in PTSD. Second, they promote the relaxation response that counters hyperarousal and results in a calmer approach to difficulties and challenges. Third, they may improve sleep quality. This may be important in treating PTSD because memories are encoded into long-term storage during sleep via a process known as consolidation. It is possible that the disturbed sleep which is common in PTSD (nightmares and insomnia) lead to disrupted memory consolidation. Therefore improvement in sleep may lead to improvement in PTSD.
Despite promising findings, meditation has not been sufficiently studied in Veterans to recommend its widespread use in treating PTSD. The goal of this proposal is to examine the effects of SKY meditation therapy on Veterans with clinically significant PTSD symptoms. SKY intervention will be compared to cognitive processing therapy (CPT) that is commonly used to treat Veterans with PTSD. CPT will be given as a "cognitive only" version (CPT-C) which is efficacious in treating PTSD. Veterans will be randomly assigned to one of the two groups (SKY, CPT-C; n=38 per group) and treatment will be delivered over a six-week period. A "noninferiority" experimental design will be used as is appropriate for trials in which the primary objective is to show that a novel intervention (SKY) is as effective as the standard intervention. Patients' PTSD symptoms will be monitored across time; before treatment (i.e., baseline), at the end of treatment, one month after treatment and 12 months after treatment. Other measures will be taken at baseline and at the end of treatment, and will include autonomic arousal (heart rate) and cognitive functioning including memory consolidation. The investigators will also monitor dropout rates as these can be high in conventional PTSD treatment programs. Based on preliminary studies using SKY in Veterans with PTSD and the existing literature, the investigators expect that PTSD symptom severity will be reduced following treatment with SKY, that this effect will not be clinically inferior to CPT-C and that the dropout rates will be no higher than CPT-C. Such findings would provide strong evidence for the efficacy of SKY in treating Veterans with PTSD. The investigators also expect that improvements in clinical measures of PTSD will correlate with improvements in memory consolidation, reflecting improvements in sleep following treatment. It is also likely that the individual's response to treatment will be influenced by their baseline characteristics. The SKY and CBT-C interventions focus on different aspects of PTSD; the SKY intervention focuses on breathing and relaxation techniques whereas CPT-C focuses on modifying the understanding of trauma through cognitive restructuring. For this reason the SKY intervention may be more effective for Veterans who have exaggerated arousal (e.g. heightened heart rate). In contrast the CPT-C intervention may be more effective for Veterans who have more cognitive symptoms (e.g., flashbacks, attentional difficulties) since CPT-C addresses cognitive processes. The long term goal of this project is to conduct a fully-powered multi-center randomized controlled clinical trial of SKY meditation in Veterans.

EXPERIMENTAL: SKY
a standardized meditation program
|
SKY (Sudarshan Kriya Yoga) meditation is a standardized, manual-based and replicable program that includes relaxation techniques as well as periods of discussion.
The format is a 7-day intensive group class (2 1/2 hours/day intensive format) followed by five weeks of sessions twice per week (1hr/session).
SKY meditation incorporates several types of breathing exercises involving arousal and attentional control.
Initial breathing exercises are calming and focusing.
Subsequent breathing exercises are more fully engaging energizing, allowing the practitioner to focus more fully in each moment.

ACTIVE_COMPARATOR: CPT-C
CPT-C (Cognitive Processing Therapy-cognitive only) is a standardized, manual-based treatment consisting of 12, 60-minute sessions which will be given twice per week.
Sessions will focusing on specific issues, learning new therapeutic techniques and setting up homework for the following session including real-life application of learned CPT techniques.

Change in PTSD Checklist (PCL)
Time Frame: baseline, after treatment (six weeks), one month after treatment, and one year after treatment
|
Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) (Blanchard et al., 1996) is a 17-item self- report scale that assesses PTSD symptom severity in the past month corresponding to DSM-IV criteria for PTSD.
Scores range from 17-85 with higher scores reflecting greater severity.
We used the civilian version to assess symptoms from both military and non-military trauma.

Change in Beck Depression Inventory II (BDI-II)
Time Frame: baseline, after treatment (six weeks), one month after treatment, and one year after treatment
|
The BDI-II scale is a 21-item self-report measure that assesses depression symptom severity.
Items are rated on a 4-point scale according to how much the symptom bothered the respondent over the prior two weeks.
Scores range from 0-63 with higher scores reflecting greater severity.

|
A 20-item self-report measure assessing positive and negative mood states over "the past few weeks" on a 5-point scale.
Scores for positive and negative affect range from 10-50 with higher scores reflecting stronger affect.
